WATCH-BOW FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 459,195, datedSeptember 8, 1891.

Application filed December 10, 1890. Serial No. 374.178. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES F. MORRILL, of Boston, in the county ofSuifolk and State of Massachusetts, have invented certain new and usefulImprovements in IVatch Bow Fasteners, of which the following is aspecification.

This invention has for its object to provide simple and effective meansfor securing a bow to a watch-case pendant; and it consists in theimprovements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a longitudinal section of a watch-case pendant and abow secured thereto in accordance with inyinvention. Fig. 2 representsa. similar View showing a modification. Fig. 3 represents a longitudinalsection of the pendant and a side elevation of the bow, showing adifferent form of fastening device from those shown in Figs. 1 and 2.Fig. 4 represents the washer used in Fig. 1 to form a dust-tight jointaround the ends of the bow. Fig. 5 represents a longitudinal section ofthe pendant with the bow removed. Fig. 6 represents anothermodification.

The same letters of reference indicate the same parts in all thefigures.

In the drawings, a represents a watch-case pendant, having orifices b bfor the reception of the ends of the bow c. The pendant is provided withoffset enlargements a a, in which the orifices Z) Z) are formed, saidenlargements forming annular recesses (I (Z around the ends of the bowwithin the pendant, said recesses affording room for the individualfastening devices for the ends of the bow and being outside of thelongitudinal passage or opening through the pendant.

In carrying out my invention I provide a separate or individualfastening for each end of the bow, said fastenings being accommodated,as already indicated, by the recesses (Z (Z.

In Figs. 1 and 2 I have shown each fastening as a pin f, inserted in atransverse orifice formed in the inwardly-projecting portion of the bow,each end of the bow having an orifree for this purpose. The pin f islonger than the diameter of the stock or wire of which the bow is made,so that it projects at both ends from the periphery of the bow and formsa stop to prevent the withdrawal of the ends of the bow through theorifices Z].

I prefer to place washers g, of leather, rubber, or other suitablematerial, in the recesses (Z d before inserting the pins f, said washersbeing held in place by the pinsf, as shown in Fig. l,and making thejoints around thebow ends dust-tight. The pins fare inserted in theorifices formed for them in the bow ends after the latter are insertedin the pendant.

nal holes 2 1', formed for the passage of the pins in the pendant, thepins being preferably the ends of wire rods of sufficient length to bemanipulated from the outer end of the pendant, said rods being partiallycut across or weakened, so that when inserted in the orificesz' and inthe coinciding orifices in the bow the pins f maybe disconnected fromthe wire by a slight rotary movement of the latter, the pins beingdriven tightly into the orifices in the bow before the separation.

In Fig. 2 I have shown the orifices 6 as extending diagonally from theinner surface of the pendant instead of from the outer end thereof. Inthis case the piece of wire is inserted as before, and the portions thatenter the orifices in the bow are deflected from the diagonal positionwhich they assume in the inclined orifices 'L to the vertical position.which they assume in the bow.

In Fig. 3 I show as the individual fasten in g devices two screw-caps)"f, screwed upon the screw-threaded ends of the bow and received whollyor partly by the recesses (Z (Z. In this case one end of the bow wouldhave a thread of opposite pitch .from that of the other, the caps f fbeing correspondingly threaded, so that the caps may be engaged with thebow by holding them so that they cannot rotate, then swinging the bow inone direction to cause its threaded ends to enter the caps, thenreleasing the caps and swinging the bow in the opposite direction, thenagain holding the caps and swinging the bow as before, and so on untilthe caps are firmly seated upon the ends of the bow.

It will be seen that in either of the constructions shown the fasteningdevices are received in the recesses 1 cl of the pendant,

' Said pins may be passed through longitudiso that they do not encroachmaterially upon the space within the pendant necessary for the receptionof the stem or winding-bar attached to the crown. The pins ff may bescrew-threaded and screwed into threaded holes in the bow. In the largersizes of pendants the recesses cl d 'in the sides of the pendant may beomitted and the bow ends secured by the independent fastening devicesplaced within the opening through the pendant, as shown in Fig. 6, theends of the bow being separated by a space of sufficient width toreceive the winding-bar. I prefer to use a bow with the recesses (Z (Z,however, because said recesses permitthe bow-securin g devices to belocated wholly or mainly outside the interior of the pendant, so thatroom is afforded for the insertion of a screw-threaded tube into thependant, the latter being internally threaded, said tube constituting apendant hands-setting attachment.

I claim-- 1. The combination of a pendant having orifices in its sidesto receive the ends of the bow and internal recesses surrounding saidorifices, of thebow having its ends projecting into said recesses,independent fastening devices engaged with the ends of the bow withinthe recesses, and washers held in place in the recesses by saidfastening devices, as set forth.

2. The combination of a pendant having orifices in its sides to receivethe ends of the CHARLES F. MORRILL.
